I too, would like to know for sure! I'm retired and have carried knives since I was a boy. I was thinking of purchasing a Camillus Dominator Tanto, but have put it on hold for now. I've called many local authorities and the State Police and haven't got the same answer twice! It appears to be a gray area. The state says any knife opened by mechanical device is a FELONY, in my opinion, assisted openers fall into that catagory! Mind you, this is only my opinion, but I wouldn't want to take the chance!!
I don't know how to find out, but getting caught with one just may make for a long afternoon!
